Title: Coreless motor
Inventor: NISHIMURA FUTOSHI
IPC: H02K23/58
Filed: 1987-04-24
Abstract: PURPOSE:To increase revolving torque by disposing a granular magnetic substance onto a surface of a permanent magnet opposite to a coreless-coil. CONSTITUTION:A cuppy type coreless motor 1 has a cylindrical permanent magnet 2 for a stator and internal and external yokes 4-5 while a cylindrical coreless coil 3 for an armature as a rotor is arranged concentrically in an air gap G. A magnetic fluid (a granular magnetic substance) 20 is disposed onto the surface of the permanent magnet 2 facing the coreless coil 3 at that time. Suspension in which ferromagnetic solid particulates such as ferrite are dispersed into a liquid as a base is used as the magnetic fluid. Consequently, the air gap G is shortened only by a thickness section where the magnetic fluid 20 adheres, and the reluctance of a magnetic path is lowered substantially, thus increasing magnetic flux density. Accordingly, revolving torque is augmented, thus elevating an output.

Abstract: PURPOSE:To improve the efficiency of dirt collection through prevention of interference of a water surface flow, by a method wherein the plural bathtub water suction pipes of a dirt collecting device sucking dirt on a bathtub water surface by a jet produced by discharging bathtub water through a circulating pipe are situated in parallel. CONSTITUTION:For example, two parallelly-arranged bathtub water suction pipes 11a and 11b are connected to each other at the lower part of a dirt collecting device 10 to form one pipe, and bathtub water 3 and dirt 12 are circulated to a filter 13. In which case, an injection port 7 formed ahead of an injection nozzle 6 is directed downward, a water flow 14 is raised from the bottom of a bathtub 8 to the side opposite to the dirt collecting device 10, and is branched into two directions on both sides. In which case, bathtub water suction pipes 11a and 116 of the dirt collecting device 10 suck bathtub water independently in relation to water flows from two directions from both sides, and a trouble, in which the flows in two directions on both sides interfer with each other, is prevented. This constitution improves the efficiency of dirt collection, and enables execution of rapid collecting action.

Title: Automatic focusing device
Inventor: HAMADA MASATAKA
IPC: G02B7/34
Filed: 1987-04-24
Abstract: PURPOSE:To simply finding out the driving distance of a lens and to improve the following accuracy of focus adjustment to a moving object by inhibiting correction and controlling the correction of a photographing lens when lens driving is to be accelerated from a lens stop state increasing an error up to the maximum speed. CONSTITUTION:Integration for focus detection is executed during the driving of the photographing lens, and the lens is driven at the maximum speed because a defocused value is large in case of correcting the lens driving distance during integration based on the integrated result, correction following the movement of he lens by a moving distance correcting means is not executed at least during a period from the lens stop state up to the maximum speed. When the photographing lens is driven at a low speed at the time of low defocused value, a lens driving value during integration at the time of acceleration is calculated as a correction value and the photographing lens is controlled in accordance with the correction value.

Title: Ignition control device for internal combustion engine
Inventor: KAJITA YUJI
IPC: F02P3/08
Filed: 1994-05-18
Abstract: PURPOSE:To improve an operation feeling during regulation of ignition. CONSTITUTION:A fixed angle position signal synchronized with rotation of an internal combustion engine is outputted from comparators 11 and 12 and an ignition timing signal is generated by an ignition timing computing circuit 13 according to the signal. In an F-V circuit 26, an F-V capacitor 31 to output a voltage proportioning the number of signals per a unit time is charged for a specified time at every fixed angle position and discharged at other period than the above. In a signal nullifying circuit 27, the output voltage of the capacitor 31 is compared with a reference voltage equivalent to an overspend area by a comparator 35 during the filling period of the F-V capacitor 31. When the former exceeds the latter, an ignition nullifying signal by means of which an ignition timing signal is nullified is outputted. Further, during discharge of the capacitor, the reference voltage is switched from a value equivalent to an overspend area to a different value sufficiently lower than the former value. A thyrister is turned ON by an ignition circuit 4 by means of an ignition signal fed through an AND circuit 3 and an ignition plug is caused to generate ignition sparkling.
